Online Purchase Processing System and Method

ABSTRACT

A system and method to use quick response (QR) codes encoded with merchant website identification codes and session GUID to register a user or code scanner with a merchant server, login the user or code scanner with the merchant server, and complete a purchase of an item or service within a virtual shopping cart of the merchant server. A code scanner can scan a QR code displayed on a device connected to the internet. An application server can receive an identification code from the code scanner and then transmit data indicating form fields to be filled in on a merchant webpage. A user profile can include data regarding the user and a payment instrument. The user profile data can prepopulate the form fields and the form field data can be transmitted to the merchant server to use for logging in the user and completing the purchase.

PRIORITY CLAIMS

This application claims the benefit of GB Application No. 1119375.2, filed Nov. 10, 2011, and claims the benefit of U.S. Provisional Application No. 61/587,416, filed Jan. 17, 2012. GB Application 1119375.2 and U.S. Provisional Application No. 61/587,416 are incorporated herein by reference for all purposes.

BACKGROUND

Online purchasing of goods or services from an e-commerce website generally includes at least three stages, namely registration, login, and purchase.

A user who accesses a conventional online merchant website for the first time can generally browse and select a number of items offered by the merchant, either goods or services, which the user wishes to purchase. The selected items are added to a virtual shopping cart. When then user's selection is complete, the user navigates to a checkout section of the merchant website. The user is usually required to register by completing a registration form. Registration particulars that can be required vary from one merchant website to another but typically include the user's first name, last name, email address, a selected password (usually entered twice, for safety), a physical address, and telephone number. The user can be required to formulate one or more security questions together with corresponding answers, or to answer some predetermined security questions.

It is known that such a registration process is time-consuming and tedious, involving several steps, causing a significant proportion of users to become discouraged and to leave the registration process and to abandon the virtual shopping cart altogether without completing a purchase. The merchant is left with no information about users who do not complete the registration process.

It is nevertheless desirable for merchant websites to persist with comprehensive registration requirements in order to be able to track their registered users and monitor which users are showing interest in the website, and to identify their likes and dislikes. Thus, a registration process gives rise to a trade-off between user drop-off (i.e. users who do not complete the registration process) and the ability to gain good insight into users who do complete the registration process.

If, on the other hand, the user who navigates to the checkout section of the merchant website has previously registered with the site, the user will still be required to login to the site in order to authenticate the user and complete the user's purchase. This will require the user to memorize a username (for example an email address) and a password corresponding to the merchant website. As the user registers with more merchant websites, the number of unique username and password combinations that must be memorized increases, which is cumbersome. In order to alleviate this difficulty, the user can record the username and password combinations, for example on paper or digitally, resulting in decreased security. Alternatively, the user can employ the same username and password combination across multiple merchant websites, which is contrary to best practice.

The applicant has appreciated the desirability of a simpler process for conducting online purchases than that described above.

OVERVIEW

Example embodiments are described herein. In one respect, an example embodiment takes the form of a method comprising (i) decoding, at a code scanner, a registration quick response (QR) code scanned by the code scanner from a webpage of a merchant server, (ii) transmitting, from the code scanner to a call-back registration uniform resource locator (URL) of the merchant server, registration data to register a user with merchant server, (iii) receiving, at the code scanner after registration of the user, login credentials for logging the registered user onto the merchant server, and (iv) storing the login credentials at the code scanner.

II. Example Architecture

FIG. 1 depicts a schematic representation of a system 100 for conducting online purchases from a merchant website in accordance with example embodiments described herein. The system 100 includes an application server 102, a merchant server 104 which a merchant uses to operate an online merchant website (not shown) offering goods or services for sale, and a code scanner 106 device configured to scan and decode Quick Response (QR) codes which are well known and widely used. The code scanner 106 can take the form of a conventional smartphone handset provisioned with software for scanning QR codes, a web browser, and a wireless connection to the internet. The code scanner 106 can be referred to as “mobile wireless communication device,” a “mobile smartphone handset” or, more simply, a “mobile smartphone” or “smartphone.” As an example, the mobile wireless communication device can be a personal digital assistant or a cellular telephone. As another example, the mobile wireless communication device can be an iPhone, such as the iPhone5, or an iPad sold by Apple Inc., Cupertino, Calif., United States. The code scanner 106 does not need to be a mobile device, but can be a device that remains attached to a stationary internet-enabled device. The application server 102, the merchant server 104, and the code scanner 106 can communicate with each other using a communication network 108. The communication network 108 can comprise a wide-area network, such as the internet.

Communication between the application server 102 and the code scanner 106 can be facilitated by using a server-hosted program (not shown) and a scanner application program (a ‘scanner app’) that is installed and executed on the code scanner 106. In another respect, communication between the application server 102 and code scanner 106 can occur using network interface 152 (shown in FIG. 15) and network interface 176 (shown in FIG. 17).

A user can download a copy of the scanner app from a download repository (for example, data storage device 178 in FIG. 16) and install the scanner app on the code scanner 106. On, during, or after installation, the scanner app creates a user profile 110 on the code scanner 106 and prompts the user to manually provide personal attributes such as, the user's first name, the user's last name, a default username and password combination, an e-mail address, a physical address and particulars of one or more payment instruments such as credit cards, debit cards, e-wallets and the like. In accordance with at least some example embodiments, the user profile 110 (for example, the data in the user profile 110) is stored locally on the code scanner 106 and is not passed to the application server 102.

The application server 102 hosts a merchant portal website 120 that enables online merchants to register and create individual merchant profiles that are maintained by the application server 102 in a merchant database 112. The merchant portal website 120 can be referred to as a “portal website.” Merchant registration and creation of a merchant profile in the merchant database 112 can be performed online by the merchant portal website 120. A merchant can use a merchant computing device 130 including a display for displaying websites to display merchant portal websites and an input device for selecting or entering data onto the merchant portal websites.

FIG. 2 shows an example webpage 200 of the merchant portal website 120. The webpage 200 can display a registration form 201 that a merchant can complete in order to register with the merchant portal website 120. The webpage 200 can be a homepage of the merchant portal website 120. As an example, the registration form 201 can include the following fields: a merchant's business name 202, a merchant's business address 204, and a description of the merchant's business 206. As an example, the business description can be a shoe store, an automobile parts store, a sports equipment store, or some other business description. Other examples of fields on the registration form 201 are possible. Entering data into the registration form 201 can occur, for example, by typing data or selecting data from a list of predetermined data.

FIG. 3 shows another webpage 208 of the merchant portal website 120. The merchant can use webpage 208 to add, delete, or edit any of the merchant's websites online that the merchant wishes to configure for QR-based registration, login (for example, logon) or purchasing. The webpage 208 displays merchant websites 210 and 212, shown as Merchant Site 1 and Merchant Site 2 respectively, that have been registered with merchant portal website 120. The webpage 208 displays an icon 214 that is selectable (for example, by a merchant) to configure an additional merchant website for QR-based registration, login, or purchasing. Icon 214 can be a hyperlink.

FIG. 4 illustrates another example webpage 216 of the merchant portal website 120. The webpage 216 can display a configuration form 228 for configuring websites (for example, websites 210 and 212) registered with merchant portal website 120. As an example, the configuration form 228 can include the following fields: a name of the respective merchant website 218, an image or logo 220 associated with the respective merchant website, a URL 222 of a call-back registration page of the merchant website, a URL 224 of a call-back login page of the merchant website, and a URL 226 of a call-back checkout page of the merchant website. An image or logo entered via image or logo field 220 can be displayed on a scanner app display (for example, scanner app display 950 shown in FIG. 12).

A merchant can, in this manner, configure one or more online websites for QR-based registration, login or checkout by providing these additional configuration parameters for each merchant website. The application server 102 can assign a unique merchant website identification code to each merchant website configured in this manner and the website identification code is stored in the merchant's profile in the merchant database 112. Additionally or alternatively, each merchant website identification code can be provided to and stored with a QR source that serves QR codes to the merchant server 104. For the sake of being brief, a merchant website identification code can be referred to as a “website identification code” or an “identification code.”

The merchant server 104 can maintain, in a customer database 114, individual profiles of customers registered with the merchant websites. In this description the terms ‘user’ and ‘customer’ and ‘purchaser’ are used interchangeably depending on the context. For example a user, once registered with the merchant website, becomes a customer of the merchant.

FIG. 14 illustrates an example QR code 999. QR code 999 can be encoded as a registration QR code. Alternatively, QR code 999 can be encoded as a log-in QR code. Alternatively, QR code 999 can be encoded as a checkout QR code.

III. Example Operation

A. QR-Based Registration

The system 100 can be used to register a non-registered user at a merchant website by use of the code scanner 106. Upon being registered with the merchant website, the non-registered user becomes a registered user. In use, the user (for example, a would-be purchaser of goods or services) uses a web browser on the internet-enabled device 116, such as a desktop computer, laptop computer or tablet, to browse a merchant website that has been configured for QR-based registration, login or checkout as described above. The user browses the website for goods or services offered by the merchant and can select items to purchase by adding these items to a virtual shopping cart associated with the website. If the user is a first-time visitor to the merchant website, for example, a non-registered user, it may be necessary for the user to register on the website prior to completing the purchase. The phrase “an internet-enabled device connected to an internet” is used to refer to an internet-enabled device that is configured to connect to the internet wirelessly (for example, using an air interface), via a wire connection (for example, a coaxial cable or an Ethernet cable), or via some other manner.

FIG. 5 is a flow chart depicting a set of functions 550 that can be carried out in accordance with an example embodiment. The set of functions 550 can be performed to register the user at a merchant website. Registering the user at the merchant website can be referred to as registering the user at the merchant server or registering the user with the merchant. The set of functions 550 are shown within blocks 500 through 538. A description of those blocks now follows.

At block 500, the merchant server 104 provides a registration form of a merchant website. The registration form can be provided to the internet-enabled device 116 via the communication network 108. The internet-enabled device 116 can display a registration webpage including, for example, the registration form displaying the user attributes (for example, data fields) the merchant uses to register the user. Some of the data fields of the registration form can be mandatory for registering the user and some of the data fields of the registration form can be optional for registering the user. As an example, the data fields for the user's first or last names may be mandatory data fields. As another example, the data fields for a selected username and password may be mandatory data fields. Alternatively, the data fields for the selected username and password may be optional such that the merchant server 104 assigns the user a username and password for storage in a user profile 110. The user can, of course, fill in the data fields manually at the internet-enabled device 116 in order to register on the merchant website.

At block 502, the merchant server 104 provides a registration QR code. A unique identification code that was assigned to the merchant website by the application server 102 and a globally unique identifier (‘GUID’) assigned by the merchant server 104 and that operates as a session identifier are encoded in the registration QR code. The registration QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The registration QR code and registration form can be provided, individually or in combination, to the internet-enabled device 116, which subsequently displays the registration form and the registration QR code. The registration QR code and registration form can be provided to the internet-enabled device 116 as part of a registration webpage the internet-enabled device 116 can display.

At block 504, the user can use the scanner app 164 and the scanner 156 to scan the registration QR code on the registration webpage of the merchant website. At block 506, the scanner app 164 decodes the scanned registration QR code to recover the encoded data that it contains namely, the merchant website identification code and the session GUID. A GUID encoded in a QR code can be transmitted to the merchant server 104, in communications from the code scanner 106, so that the merchant server 104 can determine which internet-enabled device to send data for updating a webpage or display at the internet-enabled device.

At block 508, the code scanner 106 or the scanner app 164 transmits the merchant website identification code to the application server 102 and requests the call-back registration URL 222 of the merchant website. At block 510, the application server 102 uses the merchant website identification code to perform a lookup in the merchant profile in the merchant database 112. At block 512, the application server 102 transmits the call-back registration URL 222 of the merchant website to the code scanner 106. The code scanner 106 provides the call-back registration URL to the scanner app 164 for further processing.

At block 514, the scanner app 164 then requests, from the merchant server 104, particulars of the registration data fields shown on the registration form provided to the internet-enabled device 116. The code scanner 106 transmits that request to the call-back registration URL of the merchant server 104. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the request for registration data fields.

At block 516, the merchant server 104 transmits, to the code scanner 106, a list of the registration data fields. Each registration data field can be flagged as being either mandatory or optional. The merchant server 104 can select the list of registration data fields based on the session GUID received from the code scanner at block 514. The code scanner 106 provides the list of the registration data fields to the scanner app 164. At block 518, the scanner app 164 displays the registration data fields on the user interface 154, indicating which data fields, if any, are mandatory. At block 520, the scanner app 164 pre-populates, as far as possible, the displayed data fields with data stored in the user profile 110.

At block 522, the user can review the pre-populated registration data fields and amend the displayed data, if necessary, and complete any data fields which are unpopulated. After reviewing and amending the data displayed in the registration data fields, the user can accept the displayed data. At block 524, the scanner app 164 causes the code scanner 106 to transmit the displayed registration data to the call-back registration URL 222 of the merchant website on the merchant server 104 in addition to the session GUID recovered from the scanned registration QR code. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the displayed registration data. After receiving the registration data from the code scanner 106, the merchant server 104 can provide the received registration data to the Internet-enabled device 116 to update the registration webpage being displayed at the internet-enabled device 116. The registration webpage can be configured to request (for example, periodically) received registration data from the call-back registration URL 222 of the merchant server 104. Additionally or alternatively, call-back registration URL of the merchant server 104 can be configured to forward the received registration data to the internet-enabled device 116 for updating the displayed registration webpage.

At block 525, the merchant server 104 can determine whether the mandatory registration data for registering the user with the merchant server 104 has been received for the user.

If all of the mandatory registration data has been received by the merchant server 104, the merchant server 104 can make a determination that registration of the user was successfully completed and proceed to block 530. At block 530, the registration page of the merchant website updates to indicate to the user that registration on the merchant website has completed successfully.

If the merchant server 104 determines that it needs at least a portion of the mandatory registration data to register the user, the merchant server 104 can proceed to block 526, where the registration page of the merchant website will refresh and populate those mandatory registration fields for which data was received from the scanner app. At block 528, the merchant server 104 can request the user to manually fill in the remaining registration fields on the website registration page.

At block 532, upon or after successfully completing registration on the merchant website, the merchant website authorises the newly-registered user's website login credentials, namely, the user's username and password and can return these credentials to the scanner app 164. At block 534, the code scanner can store the user's login credentials into the user profile 110 for subsequent use on the particular merchant website.

At block 536, the merchant server 104 can, optionally, return to the scanner app 164 any data that the user inputs manually to fill in any unpopulated website registration fields.

At block 538, the code scanner 106 stores the manually entered data, returned from the merchant server 104, into the user profile 110. The scanner app 164 can cause the code scanner 106 to store that data, which will be available for subsequent use. For example, suppose two of the website registration fields on the merchant website are a security question and a corresponding answer and, suppose further, that the user profile 110 does not include a stored security question and answer. As described, the user can manually fill in the security question and answer fields in the scanner app 164 or on the registration webpage of the merchant website. If the user fills in the two fields in the scanner app, the scanner app 164 updates the user profile 110 to include these additional two data items. If, on the other hand, the user fills in the question and answer fields on the registration webpage of the merchant website, the merchant server 104 transmits the two data items to the scanner app 164, which updates the user profile 110. In either case, the security question and corresponding answer will be available automatically to pre-populate these fields in any subsequent website registration where these data items can be entered into data fields, regardless of whether the data fields are optional or mandatory data fields.

B. QR-Based Login

If the user is not a first-time visitor to the merchant website and has previously registered with the merchant website, the user can logon to the merchant website in order to make a purchase. FIG. 6 is a flow chart depicting a set of functions 650 that can be carried out in accordance with an example embodiment. The set of functions 650 can be performed in order for the user to logon to the merchant website. As shown in FIG. 6, the set of functions 650 pertain to logging on to a merchant website and the user accessing, or being directed to, the login page of the merchant website by a web browser on the internet-enabled device 116. The set of functions 650 are shown within blocks 600 through 622. A description of those blocks now follows.

At block 600, the merchant server 104 provides a login page of merchant website. The login page can be provided to the internet-enabled device 116 via the communication network 108. The internet-enabled device 116 can display the login page including, for example, a login form displaying the user attributes (i.e. data fields) the merchant uses to login the user. Some of these data fields, such as the user's username, and password, can be mandatory. Other data fields can be optional. The user can, of course, fill in the data fields manually in order to login to the merchant website.

At block 602, the merchant server 104 provides a login QR code that encodes the identification code that was assigned to the merchant website by the application server 102 and a GUID that operates as a session identifier. The login QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The login QR code and login form can be provided, individually or in combination, to the internet-enabled device 116, which subsequently displays the login form and the login QR code. The login QR code and login form can be provided to the internet-enabled device 116 as part of a login webpage the internet-enabled device 116 can display.

At block 604, the user can use the scanner app 164 and the scanner 156 to scan the login QR code on the login page of the merchant website. At block 606, the scanner app 164 decodes the scanned login QR code to recover the encoded data that it contains, namely, the merchant website identification code and the session GUID.

At block 608, the code scanner 106 or the scanner app 164 transmits the merchant website identification code to the application server 102 and requests the call-back login URL 224 of the merchant website. At block 610, the application server 102 uses the merchant website identification code to perform a lookup in the merchant profile in the merchant database 112. At block 612, the application server 102 transmits the call-back login URL 224 of the merchant website to the code scanner 106. The code scanner 106 provides the call-back login URL 224 to the scanner app 164 for further processing.

At block 614, the scanner app 164 performs a lookup in the user profile 110 to check whether the profile contains login credentials associated with the login webpage of the merchant website that the user is seeking to logon to. If such login credentials are found in the user profile 110, the credentials, together with the session GUID, are transmitted (at block 616) to the call-back login URL of the merchant website for authentication. If the merchant server 104 successfully authenticates the transferred login credentials at block 618, the login webpage of the merchant website updates to indicate to the user that login to the merchant website has completed successfully (block 620). As an example, after authenticating the login credentials received from the code scanner 106, the merchant server 104 can provide data to the internet-enabled device 116 to update the login webpage to indicate user login was successful. The login webpage can be configured to request (for example, periodically) status of authenticating the user's login credentials. Updating the login webpage can include providing the user with access to a shopping webpage via the merchant website.

Returning to block 614, if, on the other hand, the user profile 110 does not contain login credentials associated with the login page of the merchant website, the scanner app 164 initiates, at block 622, a website registration process as if the user had scanned a registration QR code on the registration page of the merchant website, as described above.

C. QR-Based Purchasing

FIG. 7 is a flow chart depicting a set of functions 750 that can be carried out in accordance with an example embodiment. The set of functions 750 can be performed to complete a purchase transaction of goods or services, contained in a virtual shopping cart, that the user wishes to acquire from the merchant or merchant website. The user can navigate to a checkout webpage of the merchant website by means of a web browser on the internet-enabled device 116. The set of functions 750 are shown within blocks 700 through 740. A description of those blocks now follows.

At block 700, the merchant server 104 provides a virtual shopping cart and an amount due. As an example, the shopping cart and the amount due can be provided to the internet-enabled device 116 via the checkout webpage that displays the contents of the shopping cart as well as the total amount due and payable for the purchase. The merchant server 104 can provide purchase data fields for manually completing the purchase of items in the shopping cart using the internet-enabled device 116.

At block 702, the merchant server 104 provides a checkout QR code. A unique identification code that was assigned to the merchant website by the application server 102 and a GUID that operates as a session identifier are encoded within the checkout QR code. The checkout QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The checkout QR code can be provided to the internet-enabled device 116, which subsequently displays the checkout QR code for scanning by the code scanner 106. The checkout QR code can be provided to the internet-enabled device 116 as part of a checkout webpage displayable using the internet-enabled device 116.

At block 704, the user can use the scanner 156 or the scanner app 164 to scan the checkout QR code on the checkout webpage of the merchant website. At block 706, the scanner app 164 decodes the scanned checkout QR code to recover the encoded data that it contains, namely, the merchant website identification code and the session GUID.

At block 708, the code scanner 106 or the scanner app 164 transmits the merchant website identification code to the application server 102 and requests the call-back checkout URL 226 of the merchant website. At block 710, the application server 102 uses the merchant website identification code to perform a lookup in the merchant profile in the merchant database 112. At block 712, the application server 102 transmits the call-back checkout URL 226 of the merchant website to the code scanner 106. The code scanner 106 provides the call-back checkout URL to the scanner app 164 for further processing.

At block 714, the scanner app 164 requests particulars of the required purchase-data fields from the call-back checkout URL 226 of the merchant website. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the request for particulars of the required purchase-data fields. At block 716, the merchant server 104 transmits a list of the required website purchase-data fields to the scanner app 164, which typically include a shipping address, a shipping method, an amount due, and details of a payment instrument to be used (for example, a credit or debit card number, a card expiry date, a cardholder's name, a card verification code (CVC), or a personal identification number (PIN). The shipping method data field is accompanied by a choice of shipping methods offered by the merchant and the amount due data field is accompanied by the amount due and payable as displayed on the checkout page of the merchant website.

At block 718, the scanner app 164 displays the website purchase-data fields on the user interface 154. At block 720, the scanner app 164 pre-populates as far as possible, the displayed data fields with data stored in the user profile 110. In particular, the default shipping address that the scanner app 164 uses to pre-populate the shipping address data field can be the user's physical address that is stored in the user profile 110. The user can then review the pre-populated data fields and amend the displayed data if necessary and complete any data fields which are unpopulated. For example, if the user profile 110 contains more than one physical address, the user can select a different shipping address from a drop-down list the scanner app 164 displays on the user interface 154, and can select a shipping method from a further drop-down list.

At block 722, after reviewing and amending the displayed shipping information, if necessary, or any other populated purchase-data fields, the user can accept the displayed data. At block 724, the scanner app 164 transmits the purchase-data, including the shipping information, entered into the purchase-data fields, together with the session GUID, to the call-back checkout URL 226 of the merchant website on the merchant server 104. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the purchase-data. At block 725, the merchant server 104 can determine whether the shipping details have changed. If the merchant server 104 detects that the shipping address or the shipping method has changed, the merchant server 104 can, if appropriate, update the purchase amount displayed on the checkout webpage of the merchant website (block 726) and the updated purchase amount is transmitted back to the code scanner 106 (block 728) for display by the scanner app 164 (block 730). If the merchant server 104 detects that the shipping details have not changed, the process can continue at block 732.

At block 732, the user can review the purchase amount and accept the amount for payment. The scanner app 164 then transmits, at block 736, the details of a payment instrument to be used for payment (for example, a credit or debit card number, a cardholder's name, a card expiry date, a CVC, or a PIN, as stored in the user profile 110) and the session GUID to the call-back checkout URL 226 of the merchant website. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the payment instrument data. If the user profile 110 in the code scanner 106 contains details of more than one payment instrument, the user can be prompted to select a preferred payment instrument from a drop-down list displayed by the scanner app 164 (block 734).

Once the details of the selected payment instrument have been received at the call-back checkout URL, the merchant server 104 sends the particulars of the financial transaction (for example, the purchase amount, merchant and payment details) to a payment processor (not shown) for processing (at block 738). At block 739, the merchant server 104 (for example, the payment processor) can determine whether the payment was successful. The payment processor transmits a payment status indicator, for example either successful or unsuccessful. If the payment status is successful, the checkout webpage of the merchant website refreshes to indicate that the user's purchase has completed successfully (block 740). If, on the other hand, the merchant server 104 determines that the payment status is unsuccessful, the checkout webpage refreshes to request the user to select a different payment instrument and re-attempt payment (block 734). Re-attempting payment can occur using the scanner app 164 or the inter-net-enabled device 116.

If the merchant website requires the user to login before completing the purchase transaction, the user can be re-directed to the website login page. The user can login to the merchant website by scanning the login QR code displayed on the login page as described above. If the user profile 110 does not contain login credentials associated with the identification code of the merchant website, the scanner app 164 can initiate a website registration process as if the user had scanned a registration QR code on the registration page of the merchant website, as described above.

D. Additional Example Operation

FIGS. 8, 9, and 10 are flow charts that depict sets of functions that can be carried out in accordance with an alternative embodiment in which the registration, login and checkout QR codes displayed on the registration, login and checkout webpages of the merchant server 104, respectively, encode the call-back URL of the respective webpage of the merchant server 104, together with the merchant website identification code and a session GUID issued by the merchant server 104.

FIG. 8 is a flow chart depicting a set of functions 850 that can be performed to register the user at a merchant website. The set of functions 850 are shown within blocks 800 through 806 and 814 through 838. A description of those blocks now follows.

At block 800, the merchant server 104 provides a registration form of a merchant website. The registration form can be provided to the internet-enabled device 116 via the communication network 108. The internet-enabled device 116 can display a registration webpage including, for example, the registration form displaying the user attributes (for example, data fields) the merchant uses to register the user. Some of the data fields of the registration form can be mandatory for registering the user and some of the data fields of the registration form can be optional for registering the user. As an example, the data fields for the user's first or last names can be mandatory data fields. As another example, the data fields for a selected username and password can be mandatory data fields. Alternatively, the data fields for the selected username and password can be optional such that the merchant server 104 assigns the user a username and password for storage in the user profile 110. The user can, of course, fill in the data fields manually at the internet-enabled device 116 in order to register on the merchant website.

At block 802, the merchant server 104 provides a registration QR code. A unique identification code that was assigned to the merchant website by the application server 102, a GUID assigned by the merchant server 104 and that operates as a session identifier, and a call-back registration URL are encoded in the registration QR code. The registration QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The registration QR code and registration form can be provided, individually or in combination, to the internet-enabled device 116, which subsequently displays the registration form and the registration QR code. The registration QR code and registration form can be provided to the internet-enabled device 116 as part of a registration webpage the internet-enabled device 116 can display.

At block 804, the user can use the scanner app 164 and the scanner 156 to scan the registration QR code on the registration webpage of the merchant website. At block 806, the scanner app 164 decodes the scanned registration QR code to recover the encoded data that it contains namely, the merchant website identification code, the session GUID, and the call-back registration URL.

At block 814, the scanner app 164 then requests, from the merchant server 104, particulars of the registration data fields shown on the registration form provided to the internet-enabled device 116. The code scanner 106 transmits that request to the call-back registration URL of the merchant server 104. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the request for registration data fields.

At block 816, the merchant server 104 transmits, to the code scanner 106, a list of the registration data fields. Each registration data field can be flagged as being either mandatory or optional. The code scanner 106 provides the list of the registration data fields to the scanner app 164. At block 818, the scanner app 164 displays the registration data fields on the user interface 154, indicating which data fields, if any, are mandatory. At block 820, the scanner app 164 pre-populates, as far as possible, the displayed data fields with data stored in the user profile 110.

At block 822, the user can review the pre-populated registration data fields and amend the displayed data, if necessary, and complete any data fields which are unpopulated. After reviewing and amending the data displayed in the registration data fields the user can accept the displayed data. At block 824, the scanner app 164 causes the code scanner 106 to transfer the displayed registration data to the call-back registration URL of the merchant website on the merchant server 104. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the displayed registration data. After receiving the registration data from the code scanner 106, the merchant server 104 can provide the received registration data to the internet-enabled device 116 to update the registration webpage being displayed at the internet-enabled device 116. The registration webpage can be configured to request (for example, periodically) received registration data from the call-back registration URL of the merchant website. Additionally or alternatively, the call-back registration URL of the merchant website can be configured to forward the received registration data to the internet-enabled device 116 for updating the displayed registration webpage.

At block 825, the merchant server 104 can determine whether the mandatory registration data for registering the user with the merchant server 104 has been received for the user.

If all of the mandatory registration data has been received by the merchant server 104, the merchant server 104 can make a determination that registration of the user was successfully completed and proceed to block 830. At block 830, the registration page of the merchant website updates to indicate to the user that registration on the merchant website has completed successfully.

If the merchant server 104 determines that it needs at least a portion of the mandatory registration data to register the user, the merchant server 104 can proceed to block 826, where the registration page of the merchant website will refresh and populate those mandatory registration fields for which data was received from the scanner app. At block 828, the merchant server 104 can request the user to manually fill in the remaining registration fields on the website registration page.

At block 832, upon or after successfully completing registration on the merchant website, the merchant website authorises the newly-registered user's website login credentials, namely, the user's username and password and can return these credentials to the scanner app 164. At block 834, the code scanner can store the user's login credentials into the user profile 110 for subsequent use on the particular merchant website.

At block 836, the merchant server 104 can, optionally, return to the scanner app 164 any data that the user inputs manually to fill in any unpopulated website registration fields.

At block 838, the code scanner 106 stores the manually entered data, returned from the merchant server 104, into the user profile 110. The scanner app 164 can cause the code scanner 106 to store that data, which will be available for subsequent use. For example, suppose two of the website registration fields on the merchant website are a security question and a corresponding answer and, suppose further, that the user profile 110 does not include a stored security question and answer. As described, the user can manually fill in the security question and answer fields in the scanner app 164 or on the registration webpage of the merchant website. If the user fills in the two fields in the scanner app, the scanner app 164 updates the user profile 110 to include these additional two data items. If, on the other hand, the user fills in the question and answer fields on the registration webpage of the merchant website, the merchant server 104 transmits the two data items to the scanner app 164, which updates the user profile 110. In either case, the security question and corresponding answer will be available automatically to pre-populate these fields in any subsequent website registration where these data items can be entered into data fields, regardless of whether the data fields are optional or mandatory data fields.

Turning now to FIG. 9, if the user is not a first-time visitor to the merchant website and has previously registered with the merchant website, the user can logon to the merchant website in order to make a purchase. FIG. 9 is a flow chart depicting a set of functions 940 that can be carried out in accordance with an example embodiment. The set of functions 940 can be performed in order for the user to logon to the merchant website. As shown in FIG. 9, the set of functions 940 pertain to logging onto a merchant website and the user accessing, or being directed to, the login page of the merchant website by a web browser on the Internet-enabled device 116. The set of functions 940 are shown within blocks 900 through 906 and 914 through 922. A description of those blocks now follows.

At block 900, the merchant server 104 provides a login page of merchant website. The login page can be provided to the internet-enabled device 116 via the communication network 108. The internet-enabled device 116 can display the login page including, for example, a login form displaying the user attributes (i.e. data fields) the merchant uses to login the user. Some of these data fields, such as the user's username, and password, can be mandatory. Other data fields can be optional. The user can, of course, fill in the data fields manually in order to login to the merchant website.

At block 902, the merchant server 104 provides a login QR code that encodes the unique identification code that was assigned to the merchant website by the application server 102, a GUID that operates as a session identifier, and call-back login URL for the merchant website. The login QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The login QR code and login form can be provided, individually or in combination, to the internet-enabled device 116, which subsequently displays the login form and the login QR code. The login QR code and login form can be provided to the internet-enabled device 116 as part of a login webpage the internet-enabled device 116 can display.

At block 904, the user can use the scanner app 164 and the scanner 156 to scan the login QR code on the login page of the merchant website. At block 906, the scanner app 164 decodes the scanned login QR code to recover the encoded data that it contains, namely, the merchant website identification code, the session GUID, and the call-back login URL of the merchant website.

At block 914, the scanner app 164 performs a lookup in the user profile 110 to check whether the profile contains login credentials associated with the login webpage of the merchant website that the user is seeking to logon to. If such login credentials are found in the user profile 110, the credentials, together with the session GUID, are transmitted (at block 916) to the call-back login URL of the merchant website for authentication. If the merchant server 104 successfully authenticates the transferred login credentials at block 918, the login webpage of the merchant website updates to indicate to the user that login to the merchant website has completed successfully (block 920). As an example, after authenticating the login credentials received from the code scanner 106, the merchant server 104 can provide data to the internet-enabled device 116 to update the login webpage to indicate user login was successful. The login webpage can be configured to request (for example, periodically) status of authenticating the user's login credentials. Updating the login webpage can include providing the user with access to a shopping webpage via the merchant website.

Returning to block 914, if, on the other hand, the user profile 110 does not contain login credentials associated with the login page of the merchant website, the scanner app 164 initiates, at block 922, a website registration process as if the user had scanned a registration QR code on the registration page of the merchant website, as described above.

As represented in FIG. 10, in order to complete a purchase transaction of goods or services in a virtual shopping cart, the user navigates to the checkout webpage of the merchant website by means of a web browser on an internet-enabled device 116. FIG. 10 is a flow chart depicting a set of functions 1050 that can be carried out in accordance with an example embodiment. The set of functions 1050 can be performed to complete a purchase transaction of goods or services, contained in a virtual shopping cart, that the user wishes to acquire from the merchant or merchant website. The user can navigate to a checkout webpage of the merchant website by means of a web browser on the internet-enabled device 116. The set of functions 1050 are shown within blocks 1000 through 1006 and 1014 through 1040. A description of those blocks now follows.

At block 1000, the merchant server 104 provides a virtual shopping cart and an amount due. As an example, the shopping cart and the amount due can be provided to the internet-enabled device 116 via the checkout webpage that displays the contents of the shopping cart as well as the total amount due and payable for the purchase. The merchant server 104 can provide purchase data fields for manually completing the purchase of items in the shopping cart using the internet-enabled device 116.

At block 1002, the merchant server 104 provides a checkout QR code. A unique identification code that was assigned to the merchant website by the application server 102, a GUID that operates as a session identifier, and a call-back checkout URL of the merchant server 104 are encoded within the checkout QR code. The checkout QR code can be generated by the merchant server 104 or can be served to the merchant server 104 by a separate source of QR codes (not shown). The checkout QR code can be provided to the internet-enabled device 116, which subsequently displays the checkout QR code for scanning by the code scanner 106. The checkout QR code can be provided to the internet-enabled device 116 as part of a checkout webpage displayable using the internet-enabled device 116.

At block 1004, the user can use the scanner 156 or the scanner app 164 to scan the checkout QR code on the checkout webpage of the merchant website. At block 1006, the scanner app 164 decodes the scanned checkout QR code to recover the encoded data that it contains, namely, the merchant website identification code, the session GUID, and the call-back checkout URL.

At block 1014, the scanner app 164 requests particulars of the required purchase-data fields from the call-back checkout URL of the merchant website. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the request for particulars of the required purchase-data fields. At block 1016, the merchant server 104 transmits a list of the required website purchase-data fields to the scanner app 164, which typically include a shipping address, a shipping method and details of a payment instrument to be used (for example, a credit or debit card number, a card expiry date, a cardholder's name, a CVC, or a PIN. The shipping method data field is accompanied by a choice of shipping methods offered by the merchant.

At block 1018, the scanner app 164 displays the website purchase-data fields on the user interface 154. At block 1020, the scanner app 164 pre-populates as far as possible, the displayed data fields with data stored in the user profile 110. In particular, the default shipping address that the scanner app 164 uses to pre-populate the shipping address data field can be the user's physical address that is stored in the user profile 110. The user can then review the pre-populated data fields and amend the displayed data if necessary and complete any data fields which are unpopulated. For example, if the user profile 110 contains more than one physical address, the user can select a different shipping address from a drop-down list the scanner app 164 displays on the user interface 154, and can select a shipping method from a further drop-down list.

At block 1022, after reviewing and amending the displayed shipping information, if necessary, or any other populated purchase-data fields, the user can accept the displayed purchase-data. At block 1024, the scanner app 164 transmits the purchase-data, including the shipping information, entered into the purchase-data fields to the call-back checkout URL of the merchant website on the merchant server 104. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the purchase-data. At block 1025, the merchant server 104 can determine whether the shipping details have changed. If the merchant server 104 detects that the shipping address or the shipping method has changed, the merchant server 104 can, if appropriate, update the purchase amount displayed on the checkout webpage of the merchant website (block 1026) and the updated purchase amount is transmitted back to the code scanner 106 (block 1028) for display by the scanner app 164 (block 1030). If the merchant server 104 detects that the shipping details have not changed, the process can continue at block 1032.

At block 1032, the user can review the purchase amount and accept the amount for payment. The scanner app 164 then transmits, at block 1036, the details of a payment instrument to be used for payment (for example, a credit or debit card number, a cardholder's name, a card expiry date, a CVC, or a PIN, as stored in the user profile 110) to the call-back checkout URL of the merchant website. The code scanner 106 can transmit the session GUID to the merchant server 104 with or separately from the payment instrument data. If the user profile 110 in the code scanner 106 contains details of more than one payment instrument, the user can be prompted to select a preferred payment instrument from a drop-down list displayed by the scanner app 164 (block 1034).

Once the details of the selected payment instrument have been received at the call-back checkout URL, the merchant server 104 sends the particulars of the financial transaction (for example, the purchase amount, merchant and payment details) to a payment processor (not shown) for processing (at block 1038). At block 1039, the merchant server 104 (for example, the payment processor) can determine whether the payment was successful. The payment processor transmits a payment status indicator, for example either successful or unsuccessful. If the payment status is successful, the checkout webpage of the merchant website refreshes to indicate that the user's purchase has completed successfully (block 1040). If, on the other hand, the merchant server 104 determines that the payment status is unsuccessful, the checkout webpage refreshes to request the user to select a different payment instrument and re-attempt payment (block 1034). Re-attempting payment can occur using the scanner app 164 or the internet-enabled device 116.

If the merchant website requires the user to login before completing the purchase transaction, the user can be re-directed to the website login page. The user can login to the merchant website by scanning the login QR code displayed on the login page as described above. If the user profile 110 does not contain login credentials associated with the login page of the merchant website, the scanner app 164 can initiate a website registration process as if the user had scanned a registration QR code on the registration page of the merchant website, as described above.

Clearly, numerous variations and permutations are possible to the embodiments without departing from the scope of this disclosure: Some of these variations and permutations are described below.

1. In accordance with one or more of the disclosed embodiments, the scanner app 164 can enable the user to store more than one username in case the default username is already in use on a particular website. Additional usernames can be added when the user profile 110 is set up or as required during registration at a merchant website if the default username is found to be unavailable. The user can then select which username to use from a drop-down list of alternative usernames that are displayed by the scanner app 164.

2. In accordance with one or more of the disclosed embodiments, the scanner app 164 can enable the user to store multiple security questions with corresponding answers in the user profile 110 on the code scanner 106. In such an embodiment, the user can choose and answer to use for website registration purposes from a drop-down list of alternative questions displayed by the scanner app 164.

3. In accordance with one or more of the disclosed embodiments, instead of the user profile 110 being stored only on the code scanner 106, the profile can be replicated and stored on the application server 102 as well. In this embodiment, the scanner app 164 on the code scanner synchronises changes to the user profile 110 with the copy of the profile on the application server 102 as the changes occur, or periodically, or explicitly under user command. The copy of the user profile on the application server 102 can then be imported to a different code scanner, for example when the user changes smartphones or in the event the user loses or damages her code scanner 106.

4. In accordance with one or more of the disclosed embodiments, in order to improve security of the system 100, transmission of data from the user profile 110 to the merchant server 104 by the scanner app 164 can be encrypted. In order to implement this feature, the QR code displayed on the relevant page of the merchant website encodes, in addition to the unique identification code and a session-identifying GUID, an encryption key that is valid for the duration of the user session on the merchant website. The scanner app 164 decodes the scanned QR code to recover the encryption key and uses the key to encrypt data to be transmitted by the scanner app 164 to the merchant website where the received data is decrypted using the same encryption key.

5. In accordance with one or more of the disclosed embodiments, the merchant portal website 120 can enable a merchant to configure the merchant profile in the merchant database 112 to include additional information. In particular, FIG. 11 illustrates an alternative embodiment of the merchant portal website page of FIG. 3 in which a merchant can configure the following additional information for each merchant website in the merchant profile: (i) for QR-based registration, a list 228 of registration data fields required by the merchant website and a corresponding flag indicating whether each field is mandatory or optional, (ii) for QR-based login, a list 230 of login data fields required by the merchant website, and (iii) for QR-based purchasing, a list 232 of purchase-data fields required by the merchant website.

This can enable the scanner app 164 to request the lists of registration, login and purchase-data fields directly from the application server 102 instead of requesting the lists from the respective call-back registration, login and checkout URLs of the merchant website. The fields in lists 228, 230, and 232 are provided as examples and may not be required fields.

6. In accordance with one or more of the disclosed embodiments, instead of the code scanner 106 or the scanner app 164 transmitting details of a selected payment instrument to the merchant server 104 for payment processing, the code scanner 106 or the scanner app 164 can send the financial transaction particulars to the application server 102 for processing. The application server 102 can then process the payment and return a payment status indicator, either successful or unsuccessful, to the checkout webpage of the merchant website.

7. In accordance with one or more of the disclosed embodiments, each QR code displayed on the internet-enabled device 116 is unique. The variation between each unique QR code can be a unique session GUID encoded within the QR code. Refreshing a webpage displayed by the internet-enabled device 116, regardless of whether the refreshing is triggered by the merchant server 104 or the internet-enabled device 116, can include refreshing the displayed webpage with another unique QR code.

8. In accordance with one or more of the disclosed embodiments, data sent from the code scanner 106 or the scanner app 164 may be insufficient for registering a user or code scanner, logging in a user or code scanner, or completing a purchase of an item within a virtual shopping cart. Such data may be insufficient because, for example, a payment instrument card number is not correct, an expiration date on the payment instrument card is not correct, all of the data required to register or login a user or code scanner was not provided to the merchant server, or all of the data required to complete purchasing the item was not provided to the merchant server. When insufficient data is received by the merchant server 104, the merchant server 104 can transmit, to the internet-enabled device 116, a displayable notice that indicates registration, login, or completing the purchase was unsuccessful. Such notice may not indicate why the registration, login, or completing the purchase was unsuccessful. Additionally or alternatively, when insufficient data is received by the merchant server 104, the merchant server 104 can transmit, to the code scanner 106, a displayable notice that indicates registration, login, or completing the purchase was unsuccessful and why the registration, login, or completing the purchase was unsuccessful.

9. In accordance with one or more of the disclosed embodiments the user may, after reviewing the contents of the virtual shopping cart and the amount due as displayed on the checkout page of the merchant website, scan the checkout QR code (that encodes the merchant website identification code and the session GUID). The scanner app 164 decodes the scanned checkout QR code and obtains the call-back checkout URL 226 from the application server 102 as previously described. The scanner app 164 then displays a payment form with fields pertaining to a payment instrument to be used for payment (for example, a credit or debit card number, a cardholder's name, a card expiry date, a CVC, or a PIN, as stored in the user profile 110). The fields in the payment form are pre-populated with corresponding data stored in user profile 110. If the user profile contains details of more than one payment instrument, the user can be required to select a preferred payment instrument from a drop-down list displayed by the scanner app 164. The user can accept the displayed payment instrument details, whereupon, the scanner app 164 transmits the payment instrument details to the call-back checkout URL 226 for processing.

10. In accordance with one or more of the disclosed embodiments, the user interface 154 of the code scanner 106 can display a merchant webpage with one of the described QR codes described herein. Using the scanner app 164 or another selector on the code scanner 106, the QR code displayed on the code scanner 106 can be transmitted (for example, downloaded) to the code scanner 106. The code scanner 106 can store the QR code transmitted to the code scanner 106 in the data storage device 158. The scanner app 164 can decode the stored QR code to recover data encoded in the QR code. Details and examples of decoding a QR code are described in other parts of this description. Upon recovering the encoded data, the code scanner 106 or scanner app 164 can process the encoded data. Details and examples of processing data recovered from a QR code are described in other parts of this description.

The use of Quick Response technology (QR codes), as described in the example embodiments, can enable user interactions in connection with website registrations, logins and purchases to be conducted more efficiently than is possible by means of known prior art methods. Once a user has established a user profile 110, the user need only scan, by means of the code scanner 106, a QR code displayed on a merchant website in order to effect registration at, or subsequent login to, the website. The user is spared the tedium of manually completing website registration forms or having to enter login credentials. It is anticipated that the use of QR codes for website registration and login in this manner will reduce the proportion of users who can commence website registration and drop-off without completing the registration process.

When a user registers at a merchant website, login credentials for that particular website are stored in the user profile 110, for use in subsequent logins to the website, thereby avoiding the necessity for the user to memorize the login credentials. Furthermore, the user can use different login credentials for each website at which the user registers, without requiring the user to memorize or record such different credentials, resulting in improved security.

Data in the user profile 110 is stored locally in the code scanner 106. This means that sensitive user data such as particulars of payment instruments like credit or debit cards need not be stored or administered elsewhere such as, for example, the merchant server 104, thereby reducing the possibility of such particulars being misappropriated.

IV. Example Scanner Application Displays

Next, FIG. 12 illustrates example scanner app displays 950 and 952 that the scanner app 164 can provide (for example, display) in accordance with one or more of the example embodiments. Scanner app display 950 can be displayed after or in response to the code scanner 106 scanning a registration QR code, such as a registration QR code that is part of a registration webpage displayed on the internet-enabled device 116. The registration webpage can be provided by an example merchant referred to as ABC Inc. Displaying the scanner app display 950, or at least a portion of scanner app display 950, can occur as the scanner app 164 decodes the registration QR code. Additionally or alternatively, displaying the scanner app display 950 can occur after the scanner app 164 decodes the registration QR code.

The scanner app display 950 can include an existing login credential selector 958 for selecting a login credentials previously entered for the registration website and the code scanner 106 or a user of the code scanner 106. If no login credentials have been previously entered for the registration website and the code scanner 106 or the user of the code scanner 106, the existing login credential selector 958 may indicate that no login credential have been entered for the registration website. Alternatively, in such a case, the existing login credential selector 958 could be omitted from the registration scanner app display 950. If, on the other hand, login credentials have been previously entered for the registration website and the code scanner 106 or a user of the code scanner 106, the existing login credential selector 958 can be used to select the previously-entered login credentials. If multiple login credentials have been entered for the registration website, for example, login credentials for two different users of the code scanner 106, the existing login credential selector 958 can be used to initiate selecting or to select from among the multiple login credentials. Upon or after selecting login credentials using the existing login credential selector 958, the server app 164 can transition to displaying scanner app display 952 for logging on to the merchant server 104.

The scanner app display 950, for example, at the existing login credential selector 958 can be pre-populated with data regarding a merchant that provides the registrations website (for example, ABC, Inc.). The merchant data can include an icon or image associated with the merchant.

The scanner app display 950 can include a user-profile entry area 960 that displays registration fields. The user-profile entry area 960 can be included if no login credentials have been previously entered for the registration website and the code scanner 106 or a use of the code scanner 106. One or more of the registration fields, such as “First Name,” can be a mandatory field required for registration. One or more of the registration fields, such as “Title” or “Phone Number” can be optional fields that are not required for registration. Such registration field(s) can be labelled as “Optional.” One or more of the registration fields can be pre-populated with data stored in code scanner 106, such as data stored in the user profile 110. The scanner app 164 can allow a user to revise the data entered into a registration field. The user-profile entry area 960 can also be included to add additional login credentials, such as login credentials for another user of the code scanner 106.

The scanner app display 950 includes a registration selector 962 that is selectable to cause the registration data entered into the user-profile entry area 960 to be transmitted to a call-back registration URL of the merchant server 104. In one respect, the registration selector 962 can be visible, but unselectable, if no data or improper data has been entered into a or each mandatory registration field. In another respect, the registration selector 962 can be visible and selectable even if no data or improper data has been entered into a or each mandatory registration field. The scanner app 164 can be configured to detect improper data within a field, such as an improper e-mail address.

The scanner app display 952 includes a login data entry area 964 in which a user can enter login credentials, such as a “Username” and “Password.” The scanner app 164 can pre-populate login credentials, stored in the user profile 110, into the login data entry area 964. The login credentials pre-populated into the login data entry area 964 can be selected based on the identification code encoded within the registration QR code. If the code scanner 106 includes login credentials for multiple users, a portion of the login credential, such as the user password, may not be populated into the login data entry area 964 when prepopulating login credentials into the login data entry area 964 occurs. In such a case, the user may need to enter the user password prior to logging on to the merchant server.

The scanner app display 952 includes a login selector 966. Selecting login selector 966 (for example, by pressing login selector 966) can cause the scanner app 164 to transmit (block 616 in FIG. 6) the login credentials to the call-back login URL of the merchant server 104.

The scanner app display 952 includes a menu 968 showing other features of scanner app 164 that can be initiated. In accordance with another embodiment, if the code scanner 106 has already stored login credentials to log on to the merchant website, the scanner app display 952 can be displayed automatically upon scanning and decoding the registration QR code.

Next, FIG. 13 illustrates example scanner app displays 954 and 956 that the scanner app 164 can provide (for example, display) in accordance with one or more of the example embodiments. Scanner app display 954 can be displayed after or in response to the code scanner 106 scanning a registration QR code, such as a registration QR code that is part of a registration webpage displayed on the Internet-enabled device 116. The registration webpage can be provided by an example merchant referred to as ABC Inc. Displaying the scanner app display 954, or at least a portion of scanner app display 954, can occur as the scanner app 164 decodes the registration QR code. Additionally or alternatively, displaying the scanner app display 954 can occur after the scanner app 164 decodes the registration QR code. In accordance with this embodiment, the Title and phone Number Registration fields in user-profile entry area 960 are not labelled as “Optional.”

The scanner app display 954 includes an address selector 970 that is selectable to cause the scanner app 164 to display the scanner app display 956. The scanner app display 956 includes an address list 972 from which an address is selectable to include with the registration data the code scanner 106 transmits to the merchant server.
